I have implemented standard dropship process. Here in all the manual processes are done by a concurrent program (eg. Run Workflow background process, create requisition, auto-create PO etc).
There is a specific scenario where i need to update the requisition line price as per the discount factor. So need to update the line price before auto-creating PO.

Have either of you ever found the API to update requisitions from the back-end? I need to update PO Requisition Header and Line base tables and I am looking on how to update via Requisition Interface tables. Any suggestions appreciated. Thanks.
